Bug ID: 463186 Summary: Transparent pixels change the bound of layer thumbnails Classification: Applications Product: krita Version: 5.1.4 Platform: macOS (DMG) OS: macOS Status: REPORTED Severity: normal Priority: NOR Component: Layer Stack Assignee: krita-bugs-n...@kde.org Reporter: mangate...@gmail.com Target Milestone: --- Created attachment 154664 --> https://bugs.kde.org/attachment.cgi?id=154664&action=edit Observed result SUMMARY Layer thumbnails allow to quickly identify layers. Wen drawing on a small portion of the canvas, the thumbnails are zoomed on them so they can still display something meaningful to the artist. The problem is brush strokes, even when totally empty, change the bound of the image on the layer: When you look at the thumbnail, it looks empty or very zoomed out and unusable. STEPS TO REPRODUCE 1. Make a big canvas and add an empty layer on top (checkerboards) 2. Make a small mark in a corner of the canvas. Note the layer thumbnail is nice and zoomed correctly (first attachement) 3. Turn eraser mode on a classic pixel brush. Make an erasing mark on the opposite side of the canvas. The thumbnail now zoomed out to take the whole canvas. Your real content (the first little mark on the first corner, is undistinguishable) Done on a macbook pro 16" with M1 processor with macOS 12.6.1 (21G217) -- You are receiving this mail because: You are watching all bug changes.
